Silicone O-RINGS:

For Silicones the service temperatures are from -60 ℃ to 225 ℃. Some special types can be used in extreme

temperatures up to 300 ℃ and down to -100 ℃.

Silicone rubber performs well under environmental and temperature extremes. It is usually applied in automotive

and aerospace industries where flexibility and longevity are important. It is also a suitable material for parts that

need food grade for food handling equipment and appliances.

Rubber O Ring are available in the following elastomers:

• Aflas^® or Kalrez^®(FFKM)
• Acrylate Rubber(ACM)
• Butyl Rubber(IIR)
• Ethylene-propylene (EPR, EPDM)
• Ethylene Acrylate Rubber(AEM)
• Fluorocarbon (FKM/FPM)
• Fluorosilicone(FVMQ)
